On an Earth where all humans have vanished, only I and a man created for me remain.
It was a day in the year 2126.
On that day, Earth and several other planets developed a consciousness.
Earth recalled everything it had endured.

Greenhouse gases, global warming, polluted oceans, and ruined nature.
Earth had been patient for a very long time.

And finally, it made a decision.
To return everything to the beginning.
That day, everything created by humans vanished.

Cities, cars, and factories disappeared.
But the forests, oceans, and animals remained.

Thus, Earth reset the world.
And it left behind exactly one human.
That person was... . . . . . . . . . . . . . . . . . . .
But wait.
Why was I the only one left?
I'm curious about that too.
The moment I opened my eyes, I was in the middle of a forest where not a single road, let alone a house, could be seen, and there was no one around.
No phone, no food—even the civilization I knew had vanished.
But that wasn't the end of it.
A short while later, a man of my age appeared from the forest.
The problem was that this man knew absolutely nothing.
Not a name, not a home, not food, nor how to survive.
He only knew how to speak.
And I still don't know.
Why Earth left me behind.
Why it created this man.
And whether we can truly survive here.

I stared at the man who appeared before me for a long time.
Same age as me, same pajamas as me. But his face and aura were completely different from mine.
The problem was that this man truly knew nothing.
From eating to sleeping, he didn't know a single thing necessary for survival.
It meant that, in the end, I would have to teach him everything.
I let out a sigh and looked around.

Fortunately, there were quite a few dry branches scattered nearby.
We need a house.
We need to find food, and we need a place to take cover if it rains.
But how do I build a house?
I thought for a moment, then shook my head.
...Let's just try it.
If I want to survive in this world, I can't just stand still.
